OTRC: Ben Affleck pledges to live on $1.50 a day for charity

Ben Affleck is going to help raise awareness about the struggles people who live in poverty face by living on just $1.50 a day.

The Oscar-winning "Argo" star Tweeted about taking up the challenge for the Live Below The Line anti-poverty campaign. The star can only spend $1.50 on food and drink for each day he takes up the challenge.

Affleck wrote on Monday, April 22, "1.4 billion people live on less than $1.50/day. I'm joining Live #BelowTheLine on behalf of @easterncongo. Will you?"

The actor and director is participating in the Live Below The Line campaign to support the Eastern Congo Initiative. Affleck has long been involved in efforts to aid those affected by violence in Eastern Congo and has even lobbied Congress about it. He helped establish the ECI in 2010.

"We are excited to announce that Ben Affleck will be joining us in the Live Below The Line USA challenge next week. He will be supporting Eastern Congo Initiative (ECI). Join Ben, Sophia Bush, Josh Groban, and thousands of others around the world as we raise attention and funds for some of the best charities out there in the fight against extreme poverty," the statement said.

The challenge is set at $1.50 a day because, according to the Live Below the Line website, it is the accepted global figure used to define extreme poverty. The amount represents the daily budget of someone living in extreme poverty in the United States. Individuals can take up the Live Below The Line challenge for five days. It is unclear how long Affleck will take on the challenge.

Actor Hugh Jackman appeared in a promotional video for the campaign, asking people to rise up to the organization's five-day challenge. His video can be viewed below. At the time of this writing, the campaign has raised over $164,000. Donations close on May 31.
